The battery’s main purpose is to store energy and release it when it’s needed. But what happens when it releases a higher rate than it is supposed to do? We are going to look at battery discharge deeply. Furthermore, we are going to explore different discharge methods and their effects.
A high rate of battery discharge happens when a battery releases a high amount of energy in a given time. Some batteries do this as a result of quality deformation while others are just designed like this. Note that there is a big difference between these two batteries.
Let's say your lithium-ion phone battery is experiencing a high rate of discharge. You will notice that your phone is becoming hot over sudden and then starts draining power at a higher rate. Now, this happens because your battery has deformed and needs replacement immediately. Failure to do so the battery may catch fire or short circuit your phone.
When normal batteries experience this it could be due to the manufacturer's mistake, or you mishandled your battery hence causing it to deform. It's easy to avoid it by just observing battery safety and management tips.
What does a high rate of battery discharge mean
A high rate of battery discharge represents the charging and discharging capabilities of lithium batteries as compared to the ordinary rates. It is further divided into charge and discharge rates. Also, C indicates the ratio of the discharging and charging current of the battery. For example, a 2400 mAh battery 0.2 C means 480 mA (0.2 MA of the 2400 mAh battery). Conversely, 1C means 2400 mA (1 time 2400 mAh battery). Typically, the high discharge rates in batteries can be fast-charged. But because the lithium ions stick in the negative electrode as the battery charges.
This makes the process of transferring lithium ions difficult. Hence, the discharge rate is higher than the charge ratio. Grepow High C rate battery is good example of such type of a battery.
Advantages of high discharge batteries
1.It has a high performance in terms of power discharge. Also, it has more life cycles thanks to the staking process.
2.This type of battery can achieve 90C discharge, 150 C pulse for 2 seconds 5C fast charging, and 45C continuous discharge.
3.It can accommodate many applications and it's flexible in size shape and has a lightweight at the same time.
4.Because of the ultra-thin characteristics, lightweight and small size, this battery can be molded into any shape
Another example is the Gens Tattu UAV battery that is mostly used for industrial drones and UAVs. Such kinds of batteries are designed to handle high discharge rates from these devices. The only problem is that they do not store charge for a long time. And this is why you will find most drone enthusiasts carrying spare batteries in case the first one runs out.
Is a high battery discharge rate good for your battery?
If your battery is a high discharge rate battery then this is a good thing. Because it is designed to work in that manner. Furthermore, the devices that use these types of batteries require a lot of power to run. And this can only be achieved with the help of a high discharge rate battery. A good example of such devices is the drones and the UAVs.
But if it is an ordinary battery with a high discharge rate then this is a bad thing for you. Because a high discharge rate is one of the signs of a deteriorating battery. Both fast charge and high rate discharge will strip off the negative electrode hence causing quality deterioration. In some cases, a high discharge rate can cause internal short circuits. If this happens then your device can cause a fire explosion.
On the other hand, the high discharge rate is important because it provides adequate power. Various industries are developing fast charge and high discharge rate batteries to cope with the massive developing needs. For example many high-end devices such as aerial drones, UAVs, and Agricultural protection drones.
A high discharge rate is only good if it happens for the right purpose. However, all if your battery is not designed to work like this then it means that something is wrong somewhere.
Do you discharge your battery properly?
Most people are not aware that the rate of discharging matters a lot when it comes to maintaining battery quality. Because fast discharge means that you will charge it many more times than usual. Since the battery’s life is determined by the number of cycles then you will be using them a lot faster.
For example, if you have a normal lithium-ion battery that has 500 cycles, then a high discharge rate means more cycles than the normal. You can avoid it by managing your battery well. For example, following the safety guidelines.
Overloading the battery can also cause high rate discharge. So do not use more than the specified number of devices or appliances. Because they can drain the battery faster and at a higher rate. Besides this will cause the battery top strain and become weaker every day. But for batteries that are designed for high discharge rate then you have nothing to worry about. They can handle the rates without getting deformed like normal batteries.
The best way to discharge a battery is by not discharging it completely. Doing so strains the electrode and the cells hence causing it to decrease in quality. Also, storing your devices in harsh temperature conditions can cause abnormal discharging. You are advised to store them in normal room temperatures. Very cold or high temperatures can cause high discharge rates for the typical batteries.
A high rate of battery discharge stands for the charging and discharging capabilities of a lithium-ion battery in comparison to the normal rates. The symbol C stands for the ratio of the charge and the discharge. High discharge rate batteries are the best for high-end devices that ran on a lot of power such as drones and UAVs. These batteries have a high discharge rate that does not affect their performance. But normal batteries deteriorate in performance due to a high discharge rate. Note the difference!
